MUSIC-SHEET,

To all whom it may concern:

Be it known that we, HARRY L. HENTZ, of Vest Newton, in the county of Middlesex and Commonwealth of Massachusetts, and JOSEPH IV. VINAL, of Boston, in the county of Suffolk, in said Commonwealth, both citizens of the United States, have invented certain new and useful Improvements in Music-Sheets, of which the following is a specification.

The object of this invention is the construction of improved means for accenting the melody or other parts of the music be ing produced in an automatic musical instrument, the invention consisting essentially in having the note-controlling perforations of the notes to be accented associated with an imperforate section or band extending transversely across a specified portion of the music sheet, said band lying in advance of the transverse line cutting the front end of each said perforation, and, when fully covering all the tracker openings in said portion, controls the means for accenting the notes to be accented; and the note controlling perforations of the notes not to be accented being associated with other notecontrolling perforations located in the operating section and elongated so that they overlap each other and thereby control means for subduing notes not to be accented.

Referring to the drawings forming part of this specification, Figure l is a face view of a portion of a music sheet made in accordance with our invention. Fig. 2 is a side sectional elevation of a musical instrument embodying the complete invention. Fig. 3 is a front elevation, with parts broken away and parts in section, of the music sheetand associated members. Fig. 4 is a vertical side-sectional View of the same. Figs. 5 and 6 are sectional views in different positions of the switching device.

The reference numeral 1 designates the music sheet having perforations 2 and 3, of which, those numbered 2 control the notes to be accented, and the others the notes which are to be subdued. In the fragment of music sheet shown in Fig. 1, two forms of the accenting means are provided for; the perforations above the dotted line AA being adapted for the direct method, and those below, the cross-over method. In tne direct method, each section or half of the Specification of Letters Patent.

music sheet at its side of the median line BB is adapted for the accentual control of notes in the corresponding half of the musical instrument, and not of notes in the other half of the instrument. In the crossover method, the note controlling perforations and transverse bands in one half of the music sheet are adapted for the accentual control of the notes in the other half of the musical instrument, and not in its corresponding half. In said direct method, the first perforation to meet the tracker after the passage of an imperforate section or band, is the one which will cause its associated note to be accented, while the notes associated with the perforations which are overlapped by other perforations in the same half of the sheet will be subdued. In said cross-over method, the first perforation to meet the tracker in one half of the music sheet after the passage of an imperforate transverse band in the other half, is the one which will cause its associated note to be accented. e find it often preferable to employ both methods in one music sheet, for the reason that otherwise many perforations will have to be so lengthened as to materially affect the execution of the music compared with the manner in which it was originally designed to be played. For example, in the upper section of the part of the music sheet shown in Fig. 1, which is according to the direct system, the first perforation 2 in the left-hand half to follow the band located between the dotted lines 0, is the one whose associated note will be accented; but inasmuch as said perforation 2 by its elongation overlaps the following notes 8, the latter will be subdued. So also the perforation 2" following the imperforate band between the lines D, will have its associated note accented, but since it overlaps the following perforations 3, the latters associated notes will be subdued. In the right hand half of the sheet, the perforations 3 overlap and their associated notes are consequently subdued, until the band E reaches the tracker followed by the perforation 2, then the band F followed by the perforation 2 the band G followed by the perforation 2, and finally the band I'I followed by the perforation 2 All these will have their associated notes accented, but the perforations 3 which are overlapped by the perforation 2 will have their associated notes subdued. In the cross-over method, the arrangement of perforations for which is illustrated in the section of the music sheet below the dotted line AA in Fig. 1, the perforation 2 in the right hand half being preceded in the left hand half of the sheet by an imperforate band J, and the perforation 2 being preceded by the band L, both will have their associated notes accented; while the overlapping of the perforation 2 in the right hand half past the perforations 3 in the left hand half will cause the latter to have their associated notes subdued. In the same manner the perforations 2 2 2 2", 2 and 2 of the right half of the sheet, being preceded by the bands N, O, P, Q, B.- and S in the left half; and the perforations 2 and 2 of the left half being preceded by the bands M and T respectively of the right half, will each have their associated notes accented. All the perforations 3 in either half being overlapped by perforations in the other half, will have their associated notes subdued.

The preferred mechanism for our use is illustrated in Figs. 2 to 6, and is designed to enable the passage of an imperforate portion of the music sheet over the tracker to so affect the chokers usually employed in such instruments that the ar 'ival of the first perforation,in its own half if the direct, and the other half if the cross-over,will have its associated note struck more forcibly than those perforations which are preceded by overlapping perforations. Referring to Fig. 2, the numeral 4: designates the high vacuum chamber of one of the chokers of the two employed, and 5 the low vacuum chamber connected in the usual way by ports through the equalizer bellows 6. lVe, however, provide a port 7 adapted to be closed by a valve 9; the low vacuum chamber being connected with the action-bellows in the ordinary way. l i hen said valve is closed, it will be the low vacuum which will act for the operation of the hammers, but when it is open, the high vacuum will act and the blows of the hammers will be more vigorous. Although we employ two of said chokers, one for the bass half of the piano, and the other for the treble half, but one of the same is shown in the drawings, since they are alike. For the control of said valve 9 in each choker, a bellows 10 is connected therewith by a long stem 11, which bellows is deflated and the valve closed by means of a valve box 12 constructed in substantially the usual manner, as indicated in Fig. 2. hen an imperforate section of the music sheet covers the tracker 13, other air-controlling devices are caused to act and shut off the admission of air to the space beneath the diaphragm 14C in said valve box, and the valve 15 will be closed. This permits sa'd bellows 10 to inflate in the usual manner, and thereby to open the valve 9, so that the hammer actuating bellows connected therewith are conditioned for strongly operating their hammers. Consequently, the first perforation which now reaches the tracker will cause its associated note to be accented; the air being admitted through said perforation to the proper action-controlling valve in the valvebox 16 through tubes 1'? and 19 leading from the tracker opening uncovered by said perforation. This also admits air beneath said diaphragm 14; (as hereinafter described), the valve 15 rises, suction deflates the bellows 10, and the valve 9 is closed, but not until the accented note has been struck. This delay in closing the valve 9 is caused by having the bellows 1O slide along the stem thereof until the shoulder 8 is reached,

after which the further motion. of the bel-' lows carries the valve up to tightly close the port 7. lVere it not for this delay, the valve might close simultaneously with or almost before the actuation of the hammers, so that the latter would respond to the subduing effect of the low acuum instead of to the high vacuum, and thereby fail to be accentual. High vacuum being thus cut ofii' from the chamber 5, the resulting low vacuum causes all following perforations which are preceded by overlapping perforations instead of an imperforate band, to have their associated hammers operated to strike subdued blows. But every time an imperforate band reaches the tracker, one or the other of the choker-s has its low vacuum chamber 5 instantly opened to the high vacuum chamber, so that the first succeeding perforation, in its own or the other half of the sheet, will have its associated note accented. ()ur devices for thus controlling the valve 9 in each choker comprise a channel 20 connected by tubes 21, 22 to the bass choker. and a channel 23 connected by tubes 24:, 25 to the treble choker. Each said channel is formed with ports 26 adapted to be closed by pads 27 controlled by bellows 29, as shown in Figs. 3 and 4t. When a perforation in either half of the music sheet uncovers an opening in the tracker, the associated tubes 17, 30 admit air to the connected bellows 29, and thereby permits the latter to inflate and uncover its associated port 26; the suction from the vacuum chamber having deflated such bellows and closed its port during the passage of an imperforate part of the music sheet over the tracker. When any one or more of said ports 26 are open, air is ad mitted through the tube 21 to the bass choker, or through the tube 2% to the treble choker, depending upon which channel is thus put into communication with the atmosphere. Both tubes 21 and 24L pass to the switch 31 shown in Figs. 1, 5 and G, which consists of a slide 32 having three ports 33, 341 and 35, and a stationary member 36 having two ports 37, 39. The tube 21 being connected with the central port 34:, while the tube 2% is connected with the two outermost ports 33 and 35; and the port 37 being connected with the tube 22, and the port 39 with the tube 25, whenever the slide is in the position shown in Fig. 5, the bass tube 21 will be in communication with the bass choker tube 22, and the tube 24 from the treble channel 23 will be in communication with the treble choker tube 25. This causes the perforations in the bass half of the music sheet to control the bass notes; and the treble perforations, the treble notes; thus adapting the same for the direct system of control. When the slide 32 is in the position shown in Fig. 6, the bass tube 21 will communicate with the treble choker tube 25; and the treble tube 24, with the bass choker tube 22; thus adapting the same for the cross-over system of control.

By providing the music sheet with some indicating means, as a star shown in Fig. 3, and furnishing the slide 32 with a pointer 10 shown in Figs. 1 and 6, the operator can see at a glance when to shift the slide in order to change from the direct system to the cross-over system, or vice versa.

hat we claim as our invention and for which we desire Letters Patent is as follows, to wit 1. In an automatically playing and phrasing musical instrument, a perforated music sheet having notecontrolling perforations, the notes to be phrased being controlled by note-controlling perforations not associated with said notes to be phrased.

2. A perforated music sheet for mechanically played musical instruments having note-controlling perforations for the notes to be accented, and note-controlling perforations for the notes not to be accented, the subduing of the notes not to be accented be ing controlled by note-controlling perforations associated with notes being accented.

3. A perforated music sheet for mechanically played musical instruments having note-controlling perforations cut so that the note-controlling perforations whose associated notes are to be subdued are overlapped by other note-controlling perforations; said overlapping note-controlling perforations controlling the subduing of the notes to be subdued.

4. A perforated music sheet for mechanically played musical instruments having note-controlling perforations cut to form an imperforate portion or band extending transversely across a specified section of the music sheet and lying in advance of a transverse line cutting the front edges of the notecontrolling perforations whose associated notes are to be accented, said imperforate portion or band controlling the accent of the'notes to be accented.

5. A perforated music sheet for mechanically played musical instruments having note-controlling perforations cut to form an imperforate portion or band extending transversely across a specified section of the music sheet and lying in advance of a transverse line cutting the front edges of the note controlling perforations whose associated notes are to be accented, said imperforate portion or band controlling the accent of the notes to be accented, and the front edges of the perforations of the notes to be accented lying slightly in advance of the front edges of the perforations of the notes not to be accented.

In testimony that we claim the foregoing invention, we have hereunto set our hands this 20th day of March, 1911.
